<p>The KSZ8895MQX/RQX/FQX/ML is a highly-integrated, Layer 2 managed, five-port switch with numerous features designed to reduce system cost. The KSZ8895 is Automotive qualified (AEC-Q100). </p><p>The KSZ8895 family was designed to be used in for cost sensitive 10/100Mbps five-port switch systems with low power requirements. Combining on-chip termination and internal LDO regulator help minimize system cost. The KSZ8895 family supports high-performance memory bandwidth and shared memory-based switch fabric with non-blocking configuration. </p><p>The KSZ8895 family also includes an extensive feature set, including: power management, programmable rate limit and priority ratio, tag/port-based VLAN, packets filtering, four queue QoS prioritization, management interfaces, and MIB counters.</p><p>The KSZ8895 family provides multiple CPU data interfaces to effectively address both current and emerging fast Ethernet applications when port 5 is configured to separate MAC5 with SW5-MII/RMII and PHY5 with P5-MII/RMII interfaces.</p><p>The KSZ8895 family offers three configurations, providing the flexibility to meet different requirements:</p><ul><li>KSZ8895MQX/ML has 5 10/100Base-T/TX transceivers, 1 SW5-MII and 1 P5-MII interface</li><li>KSZ8895RQX has 5 10/100Base-T/TX transceivers, 1 SW5-RMII and 1 P5-RMII interface</li><li>KSZ8895FQX has 4 10/100Base-T/TX transceivers on Ports 1, 2, 3 and 5 (port 3 can be set to the fiber mode). 1 100Base-FX transceivers on Port 4. 1 SW5-MII and 1 P5-MII interface</li></ul><p>All registers of MACs and PHYs units can be managed by the SPI or the SMI interface. MIIM registers can be accessed through the MDC/MDIO interface. </p><p>EEPROM can set all control registers for the unmanaged mode. KSZ8895MQX/RQX/FQX are 128-pin PQFP package. KSZ8895ML is 128-pin LQFP package.</p><p><br></p><p>Microchip's complimentary and confidential <a href="https://www.microchip.com/en-us/support/design-help/design-check-services" rel="noopener noreferrer" target="_blank" style="color: rgb(28, 53, 94);">MicroCHECK</a> design review service, which offers insight from the initial concept to the final PCB layout, is available to customers who are using our products in their projects.
